求翻译：起重机起重货物时的吊绳（缆）夹角不宜太小（图一）或太大（图二），角度最大不宜超过120º，否则，吊绳承受的拉力太大容易断裂，角度太小则使吊绳太长，在起吊工作时，基本臂仰角将会很大容易造成系统工作压力太高。是什么意思？

Angle between the crane lifting cargo sling (cable) should not be too small (Figure 1) or too large (Figure 2), the angle should not exceed 120 º Otherwise, the sling to withstand the pull is too easy to break, then the angle is too small the sling is too long, lifting work, the basic arm elevation
